It maintains favorable dispersibility even under alkaline conditions (pH=9).

ZHQ-NFF-01 is a polyolefin quaternary ammonium salt compound. It features broad-spectrum, high efficiency, environmental friendliness, excellent drug resistance and long bacteriostatic duration, and can resist interference from organic matter. It delivers powerful killing performance against common aerobic and anaerobic bacteria including heterotrophic bacteria, iron bacteria, sulfate-reducing bacteria and fungi.

ZHQ-CCA-01 Cleaner is a chemical cleaner with excellent permeability and detergency. It contains no corrosive acids or alkalis, so it will not corrode metal equipment. It can penetrate and wet the interior of dirt deposits, making greasy dirt easy to peel off and be washed away by circulating water to achieve cleaning purposes. When used together with pre-filming agent, it can strengthen pre-filming effect and improve the corrosion inhibition performance of metal equipment.

This product consists of high-efficiency defoaming agents and emulsifiers. It can eliminate foam generated by foaming substances in water, featuring strong defoaming performance and wide application range.

ZHQ-AT-01 Fatty Acid Type Diesel Anti-wear Agent is a high-efficiency diesel anti-wear agent mainly composed of various fatty acids. It effectively compensates for the degraded lubricity of diesel caused by desulfurization and refining. A small dosage can greatly improve diesel lubricity and anti-wear performance, and effectively reduce wear on relevant engine components.The product can be diluted with diesel or added directly to diesel, featuring easy uniform blending, high flash point and safe, convenient application. It burns completely along with diesel to form harmless substances and causes no pollution to the environment.

ZHQ-AT-02 fatty acid ester type diesel anti-wear agent is a low-acid product mainly composed of multiple fatty acid esters. It can effectively improve the lubricity of desulfurized refined diesel and enhance the anti-wear performance of low-sulfur diesel. A small dosage can greatly optimize the lubricating property of diesel and prevent wear of relevant engine components.

ZHQ-AA-01 Gasoline & Diesel Antistatic Agent is specially developed to prevent static electricity generation during the transportation, loading and unloading of fuel oils. Rapid flow of fuels tends to accumulate large amounts of static charges, which poses potential safety hazards. After addition of this antistatic agent, accumulated static charges can be safely dissipated via grounding to eliminate explosion risks.This product is widely applicable to light oils and heavy fuels including naphtha, gasoline, diesel oil and heavy oil, and can effectively improve the antistatic performance of oil products.

ZHQ-PPD-01 Diesel Pour Point Depressant can rapidly lower the freezing point of diesel oil, effectively refine wax crystals and reduce cold filter plugging point, so as to greatly improve the low-temperature fluidity of oil products. It is non-toxic, non-corrosive and features good flowability.

ZHQ-LTNI-01 Neutralization Corrosion Inhibitor

TH-PR series crude oil demulsifiers are alkyl oxide resin type products. They can effectively neutralize emulsifying media, enabling fine water droplets dispersed in crude oil to coalesce, grow larger and settle down, while the oil phase quickly rises to the top.

ZHQ-DCa crude oil decalcifier is a water-soluble agent mainly composed of small-molecule polymeric carboxylic acid, chelating agent and corrosion inhibitor. It can react with calcium ions in crude oil to form stable water-soluble chelates. Through chelation and precipitation, calcium ions are converted into water-soluble substances or water-phase sediments, which are removed along with the water phase during oil-water separation in electric desalting units.

Model ZHQ-LTIC-01 Corrosion Inhibitor for Top of Atmospheric & Vacuum Distillation Column

ZHQ-HTIC-01 High Temperature Corrosion Inhibitor is a high-efficiency film-forming oil-soluble corrosion inhibitor. It can directly protect corroded areas and form a firm chemical protective film.

ZHQ-SIS-01 Oil Slurry Antiscaling Agent is an oil-soluble antiscalant mainly composed of detergent dispersant, antioxidant and polymerization inhibitor.After adding this product, the detergent-dispersant components can prevent the agglomeration and deposition of corrosive products, inorganic salts and organic polymer particles in feedstock, thus reducing the formation of inorganic scale.

ZHQDM-01 is a self-developed light oil mercaptan remover alkali regeneration catalyst produced by Zhonghaiquan Environmental Protection New Materials Co., Ltd. It adopts activated carbon as the carrier, with cobalt sulfonated phthalocyanine and auxiliary agents as effective components. It is mainly applied to the catalytic oxidation regeneration of mercaptan removal alkali for light hydrocarbons such as liquefied petroleum gas.

ZHQEDS-01 Extraction Antigum Agent is a chemical additive specially used for the extractive distillation desulfurization of MTBE and light petroleum products. It is mainly composed of high-boiling alcohol and ether compounds and contains a certain amount of active sulfur conversion agent.This agent is added in trace amounts to sulfur-containing MTBE or light hydrocarbons. When applied in the rectification process of MTBE and light hydrocarbons, it can significantly improve the desulfurization rate of the above products.

It can automatically strengthen the contact between lean alkali liquid and liquefied petroleum gas (LPG), improve the solubility of mercaptans in the extractant and further enhance the reaction activity between extractant and mercaptans. Meanwhile, it increases the oxygen solubility in rich alkali liquid to accelerate the oxidation reaction of rich alkali liquid, and improves the selectivity of mercaptan oxidation to disulfides in rich alkali liquid. With sufficient air supply, the mercaptan conversion rate can be close to 100%.
